Lab1: Human Performance, Fitt's Law

Note:2 or more subjects required. Can be students themselves.

Paul Fitts found a predictable relationship between the size of a target,
the distance we have to move to it, and the speed at which we can tap, point
at, click, or whatever on it. Today we'll do experiments to try to determine
this relationship. The typical Fitts' Law experiment involves alternating
tapping on two targets. Another variant involves targets appearing randomly
in a field, and tapping those.

The first experiments you'll do will involve measuring Fitt's Law using
good old pencil and paper. The tapping task template can be found here:

For the final set of experiments, you'll use the Fitts' Law "IDTest"
from IBM Almaden.
Measure any two devices of choice (e.g. large vs. small mouse, mouse vs.
trackball, touchpad vs. trackpoint, mice with very difference shape)

Analyze and compare performance of the two devices

HINTS:

Find tasks with big differences between devices.
